Hot circulating water is distributed over the fill media and directly contacts the airflow, enabling efficient heat transfer through evaporation.
Optimized water distribution and air-water contact provide effective and stable cooling performance for continuous industrial operation.
The FRP structure offers excellent corrosion resistance, weather resistance and durability for demanding industrial environments.
Designed for applications requiring large volumes of circulating cooling water, making it suitable for centralized plant cooling systems.
The open-circuit structure eliminates the internal heat exchange coil used in closed-circuit towers, providing a practical and economical cooling solution.
The straightforward tower structure allows convenient access for inspection, cleaning and routine maintenance.
Hot water from the process or condenser system enters the upper distribution system and is evenly sprayed over the fill media.
As the water flows downward, ambient air passes through the tower and comes into direct contact with the water. A small portion of the water evaporates, removing heat from the circulating water.
The cooled water is collected in the basin and returned to the central cooling system.
Hot Water → Water Distribution → Fill → Air-Water Contact → Evaporative Heat Rejection → Cooled Water
Open-circuit cooling towers rely on direct water-to-air contact and evaporative heat transfer, which is the fundamental difference from closed-circuit towers.
Choosing between an open and closed cooling tower depends mainly on whether the process fluid can directly contact ambient air.

Industrial cooling experience
Designed for large factories and industrial facilities with high cooling water demand, the Square Open-Circuit Cooling Tower is ideal for centralized circulating water systems serving multiple production lines or equipment.
It is particularly suitable for applications requiring large water flow, continuous operation and cost-effective heat rejection, where direct contact between circulating water and ambient air is acceptable.
Typical Applications:
Large Manufacturing Plants · Plastic Processing · Chemical Processing · Metal Processing · Electroplating · HVAC & Chiller Systems · Industrial Process Cooling
An open-circuit cooling tower cools circulating water through direct contact with ambient air. Part of the water evaporates during the process, removing heat from the remaining water.
In an open-circuit tower, the circulating water directly contacts the air. In a closed-circuit tower, the process fluid remains inside a heat exchange coil and is isolated from the atmosphere.
It is especially suitable for large factories, centralized cooling systems, HVAC condenser water and industrial processes that require large volumes of circulating cooling water.
Yes. Since the circulating water is exposed to air, appropriate water treatment and regular maintenance are important to control scaling, corrosion, fouling and biological growth.
Selection should be based on actual operating conditions, including circulating water flow rate, inlet and outlet water temperatures, ambient wet-bulb temperature and site conditions.
